Obama will make his first stop in San Jose, where he's scheduled to arrive on Wednesday and stay overnight.

The White House says he will attend political fundraisers in the heart of Silicon Valley Thursday before flying to Los Angeles, where he'll also attend Democratic fundraisers and tape an interview with Ellen DeGeneres.

People should give themselves an extra 20 to 30 minutes to get to their destinations, the L.A. Police Department's Tony Im told KPCC. He also offered some other advice.

"We're going to have a lot of onlookers wanting to get a glimpse of the president, so they might not be paying attention to the road, so please be careful you're not driving too close to the person in front of you and potentially get into a car accident," Im said.

The LAPD released this list of areas that could experience traffic delays due to Obama's visit:

Obama's appearance on "The Ellen DeGeneres Show" will air Friday, when he's scheduled to leave the state.

Obama has visited California some two dozen times during his presidency. He was last in Southern California in December, when he visited relatives of the 14 people killed in a shooting in San Bernardino.
